ntrnovso FINE-Tesi.' Tosca.

Be it known that I, GEORGE E. SHAW, of the city of Pittsburg, in` the county of Allegheny, and State of Pennsylvania, have invented an improved and new Torch -or Fire-Brand, adaptable to any of the carbon oil fire-testers now in use, yby which a more uniformi. application of the dame can be made to the oil undergoing the test than' is generally donde.I My new {ire-test torch consists in a small lamp pivoted on a fixed centre fast on a clamp Vaud in the accompanying drawings- -Figure 1 represents a front View of my ire-test torch.

Figure 2 is a side view o f the same, showing Vit as attached to my improved carbon-oil tester, and indicating by dotted lines its two positions and Figure 3 is a sectional view of the'same through theline x 2:.

A represents the top part o' the carbon-oil tester, to which the clamp B is secured by the tightening of the screw D is the oil cup of the carbon-oil tester, in which the oil is placed to be' tested. The clamp B has `a projection, b, in which is a hole to receive the pivot of the piec'e E, which is secured therein by a washer and rivet, screw or otherwise. G is alamp body, made of any suitable material and shape, having the part g tted with a lid or stopper made to open for introducing' the fluid to be burnt in the torch or lamp G. In the top or stopper g of the lamp is screwed or otherwise fastened, an tube, T,.to receive u wick. AThis tube T is of the proper length, so that when the lamp` G is in the position indicated by the dottedlines in the g. 2, the flame at S will be brought to the required place o'ver the surfaceof the oil in the cup D. The wick-tube T Apasses, and can slip freely, ina hole made for that plurpose in the piece E, and is held in place and prevented from slipping by the screw H; s'o that it can be adjusted at different heights to suit different fire-testers.

The operatin of my improved tire-brand for carbomoil tester is as follows: The lamp G being'trimmed with a wick, and filled with alcohol or any other burning' Huid, can be lighted just as soon as it vis required to make a test. When it Yis required to ascertain'if the oil in the 'cup Dwll ignite, the lamp Gis lifted,` which causes it to pivot on the centre AE, and it assumes the `position indicated. by the dotted lines, having moved in the direction of the arrow No. 1. VIf the oil in 4the cup D does not'ignite, the lamp G is allowed to regainits; vertical position, which it will do spontaneously, byteason of thc gravitation of the reservoir G, and it will move in the direction of the arrow No. The reservoir G can be made of glass, so that it will always indicate the uid in it is burnt out'or not; it can he made larger 4than the drawings to suit the fire-tester for which it is intended. R is a screw, running-in a piece of metal, fastened on to the tube T, and serving', by its point resting on the top of the fire-tester or on a proper stop placed for that purpose, on the clampv B, to regulate accurately the height at whichthc ame of the torch is to approach the oil undergoing the test in the cup D.

What I claimas my invention, and. desire to secure by Letters Patent of the United States, is-

1. The torch or lamp G, pivoted, suspended, or hinged to the clamp D, or to a piece of a. fire-tester for carbon oil, so that it can be made to occupy either the vertical' position or the horzontahposition represented in iig. 2 of my drawings, or any other position between the same, in thel'manner substantially as set forth.

2. Thefcombination of the clamp D, screw C, pivoted piece E, and screw H, with the lamp G, tube T, and screw R, to make an adjustable tire-test torch, substantially as and for the purpose specified. i 3; The screw R, in combination with the tube T, piece E, and clamp B, for regulating accurately the position of thc tire-brand in relation to the oil undergoing the test.
